My time in Sinaloa has been limited to a full day, and two partial days, in October 2015. My visit was part of a train trip through the Copper Canyon of Chihuahua-Sinaloa. Other than views from the train, my time on the ground was limited to time spent in El Fuerte. Photographs from the portion of that trip which was in Sinaloa can be found at the Sinaloa, Mexico photo gallery. A video of the trip can be seen below:
A detailed description of my visit to Sinaloa is included on the the Chihuahua page. It was a singular trip and to segment it into a Chihuahua and a Sinaloa section is artificial.
